Abstract
BACKGROUND
The aging population along with the obesity epidemic has increased the number of older patients undergoing bariatric surgery. Nevertheless, there is still conflicting data regarding surgical safety in this population.
OBJECTIVES
The aim of this study was to compare the surgical morbidity of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) for older patients.
SETTING
University hospital, São Paulo, Brazil.
METHODS
We performed a prospective randomized clinical trial from September 2017 to May 2019. Obese patients aged ≥65 years were randomized to LSG or LRYGB. Data collection included demographic information, body mass index (BMI), and co-morbidities. We assessed readmission, postoperative complications, and mortality. Complications were scored according to Clavien-Dindo classification.
RESULTS
A total of 36 patients, with a BMI between 35.5 and 52.8 kg/m2 were randomized to either LSG (18 patients) or LRYGB (18 patients). The overall complication rate was similar between LSG and LRYGB (3 versus 7, P = .13). Severe complication was more prevalent in LRYGB patients but had no statistically significant difference (0 versus 3, P = .07). Each group had 1 readmission and there was no mortality in 90-day follow-up.
CONCLUSIONS
Morbidity and mortality rates of bariatric surgery are low in elderly obese patients. Despite not statistically significant, LSG had a lower rate of severe complications compared with LRYGB in this population setting.
